4 Claims.

This invention relates to a the cartridge or gun-shell type.

An object of the invention is to provide an improved coin wrapper of the character stated, t., which is so constructed as to be capable of highspeed coin reception from a rapid counting machine.

Another object is to produce a tighter and therefore safer wrapper than has beenproduced heretofore. 4 A further object of the invention is to provide a coin wrapper of the character referred to, which may be manufactured inexpensively without scrap K and waste of material, while embodying the adlf5 vantages above stated. l

Another object is to provide an improved coin wrapper of the cartridge or gun-shell type, which is so constructed as to eliminate all interference coin wrapper of with coin movement into the wrappenand` the convolutions being shown abnormally separatedv in the interest of clarity. l

The improved coin wrapper is made of a single blank' or sheet 5 of paper lor similar material, cut 3&5?. and folded as indicated. The drawing is practically to scale, and illustrates a nickel wrapper. It should be noted that the blank has two substantially parallel side edges 6 and I, and opposed ends 8 and 9. The end 8 is oblique to the'f 40 side edges, and may be disposed at an angle to the side edge l, approximately 60 degrees. This angularity, of course, may be altered or modified without departing from the invention.

The end 9 comprises a straight edge, before 45 it is folded over to form the flap I0, and said straight edge preferably, though not necessarily, is parallel to the opposite edge or end 8. By making these ends E and 9 parallel, blanks 5 may be cut from suitable sheet material continuously or 50 simultaneously, without waste and scrap to .bev

handled and disposed of.

At a point such as I2, which is about midway between the ends of edge 9, the blank is folded over upon itself, so as to form the triangular tab 55 or flap I0 whose apices are indicated by the charof alcompleted coin acters I2, I3 and I4; The'hinge or crease I5 thereby formed is not a raw cut edge like the various edges 6i, 'I, 8 and 9, and accordingly, it is comparativelyfree of extending fibers and the minute saw-tooth formations which invariably 5 characterize raw cut edges in paper stock. Moreover, the fold or hinge at I5 provides a reenforcementof a 'portionof one end of the blank, and it` more or less resiliently supports the flap, for purposes to be hereinafter explained.

It should be observedv that the end 8 is outside of the wrapper, and the end 9 is inside it, the completed wrapper being formed by merely rolling the blank of Fig. 2 from the bottom upwardly, to produce the cylindrical formation of Fig. 1. The inner end 9-I 5 is substantially spear-shaped, preferably, andthe raw out edge of end 9 is at an obtuse angle to the smooth or hinge edge- I5. The apex I 4 of the flap points toward the far end 8 of the blank.

Now, when the wrapper is formed by rolling the blank from the bottom upwardly toward end 8, the fold, crease, or hinge I5 is-bent to arcuate formation, so that I5, instead of being straight, becomes slightly curved between the points I2 and I3. The curvature, being in opposition to the tendency of the edge or hinge I5 to maintain a straight line status, imparts a strain and therefore a resiliency thereto, such as will, in the completed cylindrical wrapper, tend to maintain a close contact between the various convolutions of the Wrapper. In other words, it becomes a force opposing collapse of the inner convolution toward the' center of the cylinder. The closeness of the adjacent convolutions is not indicated in Fig. 3, because that View is merely a diagramintended to show only the number of convolutions and their relat-ionship in general.

The folded or creased edge I5 has a second function, which is that of eliminating any rough or minutely saw-toothed edge such as always characterizes a raw cut in paper. In this connection, it should be understood that the mouth of a coin wrapper must offer no resistance to the entry o-f coins from the coin counting machine, for the machine delivers coins to the wrapper at a rate of approximately 2000 per minute. Any-tendency for the innermost convolution of the wrapper to collapse inwardly of the wrapper, or to unwind, therefore, will obstruct the flow of coins into the wrapper, and will thereby result in a jam or stoppage interfering with continued operation of the counting machine. A rough or saw-toothed edge on the innermost wrapper convolution is capable of starting such a jam or stoppage, due to the fibers of the raw edge intercepting the coins and tending to draw the raw edge down into the Wrapper along with the coins as they move toward the rolled edge I6.

The mouth of the wrapper is indicated at I1, which is the port at which the coins enter the completed Wrapper. The end of the wrapper opposite the mouth I1 is closed, or partly closed, in any suitable manner, such as by upsetting the edge 'l of the blank after it has been rolled to cylindrical form, thereby to form the roll edge I6. Gun-shells of paper are similarly constructed, as

is well known, to retain the slug and the charge.

and one which will have no tendency to collapse' Y and offer resistance or obstruction to a high-speed flow of coins thereinto from the counting 'machine. Accordingly, the filling of the device with coins is highly certain and continuous, thereby eiiecting a saving of time and labor in the production of coin-lilled packages. The counting machine rarely jams the coins at the wrapper, when the wrapper is properly constructed in accordance with the teaching herein, thereby obviating much annoyance and delay in the iilling oi the wrapper with coins. Because the present construction results in what is called a tight'wrap, the liability of the lled packagev to accidental b-reakage is reduced to a minimum. Since in dieing out the blanks, the end cuts 8 and 9 are parallel, no scrap is produced and all portions of the original sheet are endowed with a useful function or purpose in i the completed wrapper.

What is claimed is: l

l. A coin wrapper which comprises an velongated sheet of material rolled to cylindrical formation with one end of the sheet disposed without, and the opposite end of the sheet disposed helically within, the cylindrical formation, said helically disposed end being folded upon itself to present a smooth creased edge interiorly of the cylindrical formation, whichoffers a minimum of r' resistance to delivery of coins into the cylindrical wrapper, the flap resulting from the fold being disposed between adjacent inner convolutions of the cylindrically Wound sheet.

2. A coin package which comprises a series of coins in face to face contact with their edges collectively aligned to form a cylindrical solid body, and a wrapper wound repeatedly about the cylindrical body of coins, said wrapper comprising an elongated sheet of paper-like material havingv opposite sides and inner and outer ends, the inner end having a corner folded upc-n itself to form a ap and a smooth creased edge, the latter being oblique to the major axis of the elongated sheet, and said flap being turned iiatwise upon the wrapper to expose the resultant helically creased edge to the edges of the coins in coins in face to face contact with their edges collectively aligned to form a cylindrical solid body, and a wrapper wound repeatedly about the cylindrical body of coins, said wrapper comprising an. elongated sheet of paper-like material having inner and outer ends, and o-pposite side edges dening the mouth of the package and the opposed base thereof, the corner formed by the innerend of the wrapper meeting that side edge which deiines the package mouth, being turned upon itself toform a smooth creased edge and a ap, said creased edge extending helically and thereby being arcuately strained throughout its entire length, from the mouth of the package toward the package base, and in contact with only 4. A coin package which comprises a series of` coins in face to face contact with their edges collectively aligned to form a cylindrical solid body, and a wrapper wound repeatedly about the cylindrical body of coins, said wrapper comprising an elongated-sheet of paper-like material having inner and outer ends-and opposite side edges defining the mouth of the package and the opposed base thereof, the corner formed by the inner end of `the, wrapper meeting that side edge which defines the package mouth, being turned upon itself to form a ap with a smooth creased edge disposed obliquely to the major axis of the elongated wrapper, said creased edge extending from the mouth of the package helically toward the package base, in contact' with only vthe edges of coins fromthe mouth inwardly, the flap lying flatwise. upon that face of the Wrapper which forms an intermediate convolution of the wound wrapper, whereby all edges of the flap, excepting the creased edge, are disposed between the wrapper convolutions and out of contact with the coin edges.
